[PATCH] penguin logo code

[Geert Uytterhoeven]

### Comments for changeset
The penguin logo resides in normal RAM, not in frame buffer memory, so we must
not use fb_readb()

### Comments for drivers/video/fbcon.c
The penguin logo resides in normal RAM, not in frame buffer memory, so we must
not use fb_readb()

Just an idea, (and slightly off-topic), but would it be possible, (I.E. not a copyright infringement, and not liable to mess up any checksums anywhere), to replace the logo that typically occurs in X86 BIOSen and fades away at boot, with a penguin?

I think the LinuxBios project made very clear that it is. What's shown on 
boot time is quite arbitrary, the main thing is what happens. But would 
you really want to _fade_away_ a penguin?

Yes. However it is by no means trivial, and aparently rather
easy to screw up.

will give you a few hundred places to begin.

Yes, I tried this once, but I never did get anything to display properly
(I _did_ remove the "energy star" logo though).  What I _was_ able to do
was put etherboot into my BIOS (which formerly only had Novel RPLboot
and not PXE).

Cheers, Andreas
